    "description": "This visualization shows NASA’s fleet of Mars orbiters, landers, and rovers during the planet’s close encounter with Comet Siding Spring. C/2013 A1, better known as Comet Siding Spring, will make a remarkably close pass of Mars on October 19, 2014. At closest approach, Comet Siding Spring will come within 82,000 miles of the Red Planet – just one-third of the distance from the Earth to the Moon. During the flyby, NASA will position its Mars fleet both to protect it from comet dust, and to make observations of the comet and its effects on the upper atmosphere of Mars. || ",

Traveling at 33 miles per second and weighing as much as a small mountain, the comet hails from the outer fringes of our solar system, originating in a region of icy debris known as the Oort cloud.Comets from the Oort cloud are both ancient and rare. Since this is Comet Siding Spring’s first trip through the inner solar system, scientists are excited to learn more about its composition and the effects of its gas and dust on the Mars upper atmosphere.NASA will be watching closely before, during, and after the flyby with its entire fleet of Mars orbiters and rovers, along with the Hubble Space Telescope and dozens of instruments on Earth. The encounter is certain to teach us more about Oort cloud comets, the Martian atmosphere, and the solar system’s earliest ingredients. || ",
